Use Dataflow Gen2 for multiple tables ingest dinamically

amaaiia If I understand you correctly, how about having another table in the LH that contains 1 value only, namely the months_to_reload  value? 

So for each delete-update cycle, in the DFg2, you read in this value in its own M query. Your other queries then can access the value. When the main query is done with its processing, you have another query that updates the months_to_reload value and publishes it back to the LH in replace mode.  

Would that do the trick or am I missing something?
